目的本研究考察了人工耳蜗（CI）使用者对元音同时呈现的感知（即，方法对10名CI受试者进行双元音和单元音的识别测试。元音的基频（F0）为100 + 100 Hz或100 + 300 Hz。元音的呈现要么是同步的，要么是延迟的。在"双元音"阶段，受试者只听到双元音。在“双+单”的会议，而双元音和单元音，受试者报告的元音的数量和身份（S）。除了临床设置，刺激通过一个实验方法，交错脉冲流的两个vowels.ResultsAlthough元音之间的时间延迟有很大的影响识别，在基本频率（Δ F0）的变化的影响是温和的。枚举是穷人的一般情况下，和识别同步元音以上的机会，只有在双会议与先验知识介绍。交错呈现的元音流提供了没有任何好处的识别和Enumeration.ConclusionsThe结果表明情节上下文CI用户的重要性的边际效益。不可靠的感知的多重性，在目前的结果表明，听觉分组CI可能是由一个基于图式的过程。
PurposeThe present study examined cochlear implant (CI) users' perception of vowels presented concurrently (i.e.,double vowels) to further our understanding of auditory grouping in electric hearing.MethodIdentification of double vowels and single vowels was measured with 10 CI subjects. Fundamental frequencies (F0s) of vowels were either 100 + 100 Hz or 100 + 300 Hz. Vowels were presented either synchronously or with a time delay. In “Double” sessions, subjects were given only double vowels. In “Double + Single” sessions, while double and single vowels were presented, subjects reported the number and identity of the vowel(s). In addition to clinical settings, stimuli were delivered via an experimental method that interleaved pulse streams of two vowels.ResultsAlthough the time delay between vowels had a large effect on identification, the effect of change in fundamental frequency (ΔF0) was modest. Enumeration was poor in general, and identification of synchronous vowels was above chance in only the Double sessions with a priori knowledge about presentation. Interleaved presentation of vowel streams provided no benefit for identification and a marginal benefit for enumeration.ConclusionsThe results demonstrate the importance of episodic context for CI users. Unreliable perception of multiplicity observed in the present results suggests that auditory grouping in CIs may be driven by a schema-based process.
